CVE-2026-50014Network attack vectorHinoki check available

Code execution via lockfile-controlled Git fetch option

Published Jun 25, 2026 · Updated Jun 25, 2026

Argument injection in pnpm before 10.34.0 and 11.0.0 through versions before 11.4.0 allows attackers to execute code via a malicious lockfile. The git fetcher appends the lockfile-controlled resolution.commit string to git fetch without a separator or hexadecimal commit validation, allowing Git to parse --upload-pack as an option. Exploitation requires a modified pnpm-lock.yaml, user execution of pnpm install, the shallow-fetch path, and an SSH or local Git transport; HTTPS ignores the injected option.
